I believe that the creative team for riot for the most part does a great job with their concepts. However, whoever decides which rewards get created chooses poro related rewards way too often. This normally wouldn't be a problem if the art didn't look almost exactly the same in each of these rewards. This goes for the worlds pickem, poro king events, gemstone/blue essence icons. new player icons, and now this cheering poro esports reward. I liked the idea of the different factions and their coat of arms/flags related to the Runeterra Map in 2017. I just believe that the world you have created could be reflected more evenly in the content you decide to reward your players.
Just my 2¢
